    Differences among breeds and manifestation of heterosis in AI boar sperm output.

  • Original language description

    A total of 271547 records of semen collections were utilised to appraise sperm characteristics of 3319 boars belonging to 8 breeds: Czech Large White (CLW), Czech Landrace (CLA), Přeštice Black-Pied (PBP), Czech Meat Pig (CM), Hampshire (HA), Duroc (DC),Pietrain (PN), Large White (LW), and various crosses of these breeds. The assessment of sperm output was based on semen volume, number of total spermatozoa and number of viable spermatozoa. A linear model was used for statistical analysis included fixedeffects of breed or crossbred combinations, boar within breed or crossbred combinations, year-season, and linear and quadratic regression on age of boars at collection and on interval between collections. The average semen volume of boars ranged from 161 ml to 349 ml.

    Diference mezi plemeny a projevy heteroze u znaků spermatu kanců

  • Czech description

    Na základě 271547 údajů od 3319 kanců byl proveden rozbor ukazatelů kvality spermatu u 8 plemen prasat: bílé ušlechtilé otcovská linie (CLW), landrase (CLA), přeštické černostrakaté (PBP), české výrazně masné (CM), hamshire (HA), duroc (DC), pietrain (PN), bílé ušlechtilé (LW) a u jejich kříženců. Sledovaly se znaky: objem spermatu, počet spermií, počet živých embryí. Pro statistické analýzy byl použit lineární model zahrnující pevný efekt plemene nebo plemenné kombinace, efekt kance uvnitř plemene nebokombinace plemen, efekt roku-sezony, lineární a kvadratickou regresi na vek kanců při odběru spermatu a na interval mezi odběry. Průměrný objem spermatu kanců byl 161 - 349 ml.
